I dunno... in fits and starts, I work on projects like...

 - noodling on my homepage and foaf file every once in a while,
  especially in preparation for trips like the TP
 - noodling on my list of past events, publications, and the like
   (I owe MIT an update to my CV)
 - formalizing DAWG records
 - the /TR/ page stuff
 - Ivan's work on /Talks/
 - timbl's roadmap diagrams
 - webarch formal descriptions

and across all those are all kinds of best-practices
issues like:

 - http://esw.w3.org/topic/PropertiesForNaming
   when to use rdfs:label vs cyc:nameOfAgent etc.
   This shows up in the tabulator, which knows rdfs:label
   and foaf:name and dc:title and maybe a few others,
   but isn't extensible (yet)

 - schema size. cyc and wordnet are nice, but they
   don't seem to be published in the web as RDF in
   stable, manageable chunks. SUMO is promising. See

 - http://esw.w3.org/topic/BuildOrBuyTerms
   when to use something out there, and when to
   make your own schema

 - schema documentation and testing. The tabulator
   will tell you when you're using (directly or indirectly)
   a schema that's 404. It doesn't catch foaf:Preson errors
   yet. We have some N3 rules that do, but they're too slow
   to be usable. Pellet is quite good for that sort of thing.

Some organizational possibilities include
 - random #swig progress
 - the SemWeb BP WG
 - the TAG
 - the recently started HCLSIG
 - PAW and TAMI research projects
 - a possible GRDDL WG-to-be
